This paper introduces a numerical method for optimally designing a passive noise control enclosure for depressing air borne noise of reciprocating engine type power generators. Sound pressure level of soundproofed power ...

Power distribution networks reduce their reliability during the fault localization, isolation and network reconfiguration. The fault localization of High voltage and medium voltage systems consumes more time and network ...

Anaerobic treatment processes have been extensively developed for the treatment of various wastewaters containing high concentrations of organic substrates including proteins, carbohydrates and lipids. The desiccated coconut ...

Tea waste generated in tea factories, which is the portion that cannot be marketed, is an abundant natural waste in Sri Lanka. Some of the tea manufacturers have converted this bulk waste into its bio-char by using pyrolysis ...

Geocells are mostly used to strengthen soft soil in many Asian countries in recent days. They provide faster, feasible and environmentally friendly solutions. In Sri Lanka however, Geocell is not much familiar soil improvement ...

This paper considers the applicability of classical lamination theory for woven composites for the analysis of bending behaviour of such composites. Although the Classical lamination theory is directly used for the analysis ...

The pedestal and table fans are widely used to provide air mixing and comfort region in enclosed spaces. There are different brand of fans with various blade shapes, sizes and number of blades which lead to different level ...

Food packaging plays an important role in preserving food throughout the distribution chain. Food packaging can delay food deterioration, keep the favourable properties of food processing, increase the shelf life or the ...
